Specification of Letters Patent.

Application filed November 2, 1908. Serial No. 460,758.

To all whom it may concern:

Be it known that I, EDWARD C. Seances, citizen of the United States,residing at Nashville, in the county of Davidson and State of Tennessee,have invented certain new and useful Improvements in Door- Stops, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention is an improved door stop or check of that class which isattached to the lower portion of a door and has a pivoted stop arm toengage the floor to hold the door in an open position.

The object of the invention is to provide a simple and practical deviceof this character which may be produced at a small cost and will bestrong and durable in use, and which may be quickly and easily thrown toeither an operative or inoperative position and will be held in suchposition by the tension of a spring.

lVith the above and other objects in view, the invention consists of thenovel features of construction and the combination and arrangement ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, in which- Figure 1 is a perspective view of aportion of a door showing the invention applied thereto; Fig. 2 is afront elevation of the same showing the stop arm swung to its elevatedor inoperative position; Fi 3 is a vertical section through the deviceshowing the stop arm in its operative position; Fig. 4 is a horizontalsection taken on the plane indicated by the line 4-l in Fig. 3; Fig. 5is a detail perspective of the attaching plate; and Fi 6 is a detailview showing the inner face of the stop arm.

In the drawings 1 denotes an attaching plate adapted to be secured toone side of a door adjacent to its bottom and to have pivotally mountedthereon a stop arm 2 for engagement with the floor. Said arm has one ofits ends engaged with a pivot 3 projecting from the attaching plate sothat it can be swung from a depending position to a horizontal positionand also to an upwardly projecting vertical position, in any one ofwhich positions it is adapted to be held by the tension of a spring andco-acting devices between its pivoted end and the attaching plate. Inthe preferred embodiment of the invention illustrated, the attachingplate is of substantially rectangular shape and has apertures atadjacent its corners to receive fastening screws or the like, but itwill be understood that said plate may be otherwise secured to the door.In the inner or bottom face of the plate is formed a recess 5 shaped toreceive a bowed or curved leaf spring 6 which actuates the pivot 3 in alongitudinal direction. Said pivot is here shown in the form of a rivetwhich passes through an aperture in the inner end of the arm 2, througha centrally arranged aperture in the attaching plate and also through acentrally arranged aperture in the spring, as clearly shown in Figs. 8and i ofthe drawings. Its purpose is to draw the pivot inwardly andthereby cause it to press the arm 2 firmly against the front or outerface of the attaching plate but at the same time permit said arm to moveoutwardly away from the plate. In order to retain the arm in any of itstwo or more positions to which it may be swung, a lug or projection 7 isformed upon the front face of the attaching plate adjacent to its pivotopenin and angularly arranged recesses or seats 8, 9, 10 are formed inthe inner face of the pivoted end of the arm to receive said lug. Asillustrated, the seats 8, 9, 10 are radially arranged and disposed inplanes at right angles to each other so that when the lug 7 is engagedwith the seat 8 the arm 2 extends downwardly to engage the floor, whensaid lug is engaged with the seat 9 the arm 2 is in a horizontalposition and when said lug is engaged with the seat 10 said arm projectsupwardly. lVhile the foregoing is the preferred arrangement of said lugand seats, it will be understood that they may be otherwise arrangedwithin the scope of the invention. The lower or outer end of the arm 2is preferably disposed at a slight angle with respect to its pivotedend, so that when the arm extends downwardly it will engage the floor alittle distance from the bottom of the door and thereby serve as abrace.

The front face of the attaching plate 1 is preferably downwardly andoutwardly inclined so that said plate is thicker at its bottom than atits top. The purpose of this inclination of the front face is to throwthe outer end of the arm 2 further away from the bottom of the door whensaid arm is in its lowered or operative position shown in Figs. 1 and 8and to throw said end of the arm closer to the side of the door whensaid arm is in its operative horizontal or vertical position. It will beseen that by reason of the downward inclination of the front face f theattaching plate, the arm will take a greater angle with respect to thevertical plane of the door when said arm is lowered and will swinginwardly toward the door when the arm is raised. The device is therebyrendered more effective as a stop or brace when in an operativeposition, and less liable to be in the way and to be caught by passingobjects when in an inoperative position. When said front face of theattaching plate has sutlieient inclination the arm 2 may be straightinstead of angular. Said outer end of the arm is preferably suppliedwith a piece 11 of rubber or other suitable material which will make aneffective friction contact with the floor. This rubber piece or pad maybe secured in any suitable manner to the stop arm.

Having thus described the invention what is claimed is:

l. A door stop comprising an attaching plate, a stop arm, a pivotuniting the arm to the plate and a spring for actuating said pivot in alongitudinal direction to press the arm against the plate.

2. A door stop comprising an attaching plate, a stop arm, a pivotuniting the arm to the plate, a spring for actuating said pivot in alongitudinal direction to press the arm against the plate andco-actingmeans upon the opposing and contacting faces of the arm and plate forretaining said arm in an adjusted position on the plate.

3. i i-door stop comprising'an attaching plate, a stop arm, a pivotuniting the arm to the plate, a spring for actuating said pivot in alongitudinal direction to press the arm against the plate, said armbeing formed upon the inner face of its pivoted end with seats and a lugupon the outer face of the attaching plate to enter said seats andretain the arm in an adjusted position.

4:. A door stop comprising an attaching plate having its face inclineddownwardly and outwardly, and a stop arm movable substantially in theplane of the door and pivoted to said inclined face'of the plate,whereby its free end will be thrown out a distance from the bottom ofthe door when said arm is in a lowered operative position, and will bethrown inwardly toward the doorwhen said arm is in an elevatedinoperative position.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
